To all whgm it may concern:

Be it known that I, SYLVESTER S. LEONARD, a subject of the King of Great Britain, residthe county of Cook and State of Illinois, have invented certain new and useful Improvements in Vacuum Devices, of-which the following is a specification.

My invention relates to improvements in vacuum devices, and is fully described and explained in this specification, and shown in the accompanying drawings, in which Figure 1 is a perspective view showing my in use. Fig. 2 is a central longitudinal section through the device, showing the parts in a different position from that shown in Fig. 1. Fig. 3 is an elevation of the rear end of the cylinder, and Fig. 4 is a section through the front end of the sliding frame.

Referring to the drawings, A is a cylinder closed at its rear end by a centrally-perforated ca a and havin at its front end a preferab y flaring mout A, having, preferably, a smooth front edge. Within the cylinder A is a movable piston B, having behind it a packing B, preferably of leather. The said packing acts as a valve to prevent air passing forward around the piston. The piston B is connected to a piston-rod B, which passes out at the rear through the central perforation in the cap a and terminates in a circular handle I). The piston B is normally pressed forward by a spring C.

The cylinder A is surrounded by'a perforated cross-piece D, which has a rearwardlyopen bayonet-slot (1, adapted to engage with a pin a on the cylinder A. The cross-piece D is rovided with rearwardly-extending rods J which are secured together by a brace D, centrally slotted forvthe passage of the handle I).

- My device is adapted primarily to produce a light suction on the skin, the same serving as a massage apparatus, although it can obviously be used in any situation where it is desired to apply light suction to any surface. For such use it is desirable to have an a paratus which can be 0 erated with equal acility with one or both hands. Ordinarily it is easier to work a device of this sort with both hands, but for general use upon the body the device must be so arranged that it can be operated with one hand or it cannot be used in many positions. When it is desired to operate the device with two hand.-:,

the sliding frame composed of the crosspiece D, brace D, and rods d is slid forward, as illustrated in Fig. 2, when it serves as a convenient handle for the cylinder. When, however, it is desired to operate the device with one hand only, the frame is slid back to the position illustrated in Fig. 1, and the bayonetslot d is engaged with the pin a. The thumb of the user can then be engaged with the handle I) while the fingers bear down on the sliding frame. In this way it is very easy to use the device with one hand in many positions where it could not otherwise be operated.

I claim as new and desire to secure by Letters Patent 1. In a device of the class described, the combination with a pump-cylinder, a piston movable therein, a piston-rodsecured to the piston and projecting from the rear of the cylinder, and a handle at the rear end of the piston-rod, of a frame slidably mounted on the cylinder, a perforation in the rear end of the frame through which the handle can pass and means for locking the frame in its rear position.

2. In a device ofthe class described, the combination with a pump-cylinder, a piston movable therein, a piston-rod secured to the piston and projecting from the rear of the cylinder, and a handle at the rear end of the piston-rod, of a frame slidably mounted on the cylinder, a perforation in the rear end of the frame through which the handle can pass and a pin-and-bayonet-slot connection between the frame and cylinder whereby the frame can be locked in its rear position.

3. In a device of the class described, the combination with a pump-cylinder, a piston movable therein, a piston-rod secured to the piston and projecting from the rear of the cylinder, and a handle at the rear of the piston-rod, of a frame slidably mounted upon the c linder, a perforation in the rear end of the i r ame through which the handle can pass, means for'locking the frame in its rear position on the cylinder, and a spring adapted to hold the piston normally forward.

4. In a device of the class described, the combination with a cylinder,a piston movable therein, a iston-rod secured. to the piston and exten g rearwardly from the cylinder and a handle at the rear of the pistonrod, of a cross-piece slidably mounted on the cylinder, rods extending rearwardly from the cross-piece on opposite sides of the cylinder,

a brace connecting the rear ends of the rods, said brace being perforated for the passage of the handle, a pin-and-bayonet-lock connection between the rear of the cylinder and the cross-piece whereby the cross-piece can be locked in its rear position.

5. In a device of the class described, the

- combination with a cylinder, a piston movable therein, a piston-rod secured to the piston and extending rearwardly from the cylinder and a handle at the rear of the pistonrod, of'a cross-piece slidably mounted on the cylinder, rods extending rearwardly from the cross-piece on opposite sides of the cylinder, a brace connecting the rear ends of the rod,

said brace being perforated for the assage of the handle, a pin-and-b'ayonet-loc connec tion between the rear of the cylinder and the cross-piece whereby the cross-piece can be locked in its rear position, and a spring exerting a forward pressure on the piston.

In witness whereof I have signed the above application for Letters Patent, at Chicago, in the county of Cook and State of Illinois, this 4th day of October, A. D. 1905.

SYLVESTER S.-LEONARD.
